PS.) What you were doing is a variation of negatives. Another way to do nagatives would be to have a training partner assist with the positive portion of the rep and then resist unassisted durring the negative portion.

Even though the lateral delts may be your target, it is possible for the front delts to take over the brunt of the exercise....if you do them standing straight up and lifting directly out to the sides. Even more so if you use a thumb up grip. If you wanna target the lateral delts more and take the front delts out of the move, try bending over a little bit and lift the weight slightly behind you, rather than directly out to the side. Also use a thumbs down grip
